Most believe the Yorkie is an ornamental breed. The truth is the Yorkshire Terrier is a sturdy breed bred from sturdy working stock. They perform incredible work tracking down vermin and are great companion dogs. The typical nature is friendly with family and strangers. Their build is 9 inches in height and carry a 7 pound maximum weight. Yorkies are small but sturdy and well built. Yorkie puppies are usually black and their brown markings begin to develop after the first few months. This is similar to the Dalmatian’s black spots.
